Sorry but I just found out what MEMS is and it's insane?? Incredibly tiny (micrometer scale) intricate clockwork mechanisms??? And they're in your iPhone?????
I mean like the specific image of clockwork in OT. That’s still lab visions.
All those other things are closer to traditional lithography for electronics. Not the tiny machines we were being promised in the 90s. I was imagining flea-sized robots back then…
I'm not sure where the disappointment is coming from. Why would anyone ever need a tiny mechanical ratchet? This stuff can be done but needs market pull (applications) because it costs $bns to overcome yield barrier.
